SPECIFICATION forming part of Letters Patent No. 617,402, dated January10, 1899.

Application filed December 21, 1896. Serial No. 616,453. (No model.)

To (r66 w/wm it may concern:

Be it known that I, DANIEL S. LONG, of Maysville, De Kalb county,Missouri, have invented certain new and useful Improvements inThreshing-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawin gs, forminga part thereof.

My invention relates to threshing-machines, and more particularly torecleaner attachments; and it consists in certain novel and peculiarfeatures of construction and combinations of parts, which will behereinafter described and claimed.

It is customary in the threshing-machines at present in use to conductthe tailings back into the cylinder to be rethreshed in order that nograin may be wasted. This operation is objectionable in that additionalwork is entailed upon the cylinder, as such tailings,comprising heads,grain,and short pieces of straw, are mixed with the unth reshed prodnot,being fed continually to the cylinder, and must be separated again fromthe same. In other words, a great deal of unnecessary work is done insuch operation, which isobviated entirely by the use of myimprovement.Furthermore, it is obvious that the capacity of the cylinder isdiminished by compelling it to reseparate material which has once passedthrough it, as such material necessarily takes the place of acorresponding volume of unthreshed straw, which might otherwise be fedinto the cylinder.

Therefore the object of my invention is to increase the capacity andrender the operation of the cylinder more efiective by preventing thegrain from passing through the cylinder a second time.

In order that the invention may be fully understood, I Will proceed todescribe it with reference to the accompanying drawings, in which- 4Figure 1 represents a skeleton side elevation of a threshing-machineembodying my invention. Fig. 2 represents a top plan view of the samewith the upper and lower decks omitted. Fig. 3 represents, on anenlarged scale, a cross-section taken on the line III III of Fig. 2.Fig. 4 represents, on an enlarged scale, the front end of the forwardelevator and the spout for conducting the tailings to the cylinder-boxor the waste to one side and upon the ground or into a receptacle toreceive it.

In the said drawings, 1 designates a threshing-machine of the type shownor of any other suitable or preferred type. It is provided with athreshing-cylinder (not shown) in the cylinder-box 2 at its front end,and extending horizontally for nearly the full length of the machine isthe lower deck 3, adapted to receive the grain and heads which areseparated from the straw asthe latter is elevated by the customarycrank-shaft or elevator (not shown) up and upon the front end of theupper deck 4, which preferably projects beyond the rear end of the lowerdeck in order that the straw may be reliably deposited upon the groundin the rear of the machine. Carried by said upper deck at its rear endis a chute 5, comprising a downwardly and forwardly inclined bottom andvertical sides. This is adapted to receive any grain or heads which maybe carried by the straw beyond the rear end of the lower deck andconduct them safely back into the grain-shoe 6, ar-

guide 5 through the opening '7 of the shoe into the grain-spout 8, whichis adapted to reciprocate back and-forth in the customary manner inorder that the passage of the grain will be facilitated. The upper andlower decks also.

are reciprocated longitudinally in the customary manner, the means foraccomplishing such action being immaterial in the present connection, asmy invention proper will Work in connection with grain-decks operatedin. any manner or by any means.

The grain-spout 8 communicates with the lower end of the casing 9, whichinclines upwardly and forwardly to a point about the middle of themachine, and travelingtherein in the customary manner is the endlesselevator '10 for conducting said tailings up through said casing. At theopposite side of the machine and also inclined upwardly and forwardly inthe same manner is a second casing 11, and said casing has its lower endopposite, but in a lower plane than the upper or discharge end of thecasing 9 and its upper end adjacent to the cylinder-box of the machine,and traveling in said casing in the customary manner is the endlesselevator 12.

Extendin g transversely of the machine is a slightly-inc1ined sifter 13,and said sifter is supported at its opposite ends upon the swingingbails 14c, suspended from the framework of the machine. Its lower endprojects into an opening in the side of the elevator-casing 11, as at15, while its opposite and upper end isarranged vertically below andcommunicating with the discharge-spout 16 of the elevator-casing 10, asshown clearly. Said sifter reciprocates longitudinally in order tofacilitate the passage of certain products composing the tailings fromthe casing 9 to the casing 11, and this reciprocatory operation is accomplished by the following mechanism:

17 designates a bracket which is secured in any suitable manner to theside of the machine adjacent to the discharge-spout of the casing 9, andjournaled transversely therein is a short shaft 18, upon the outer endof which is a belt-wheel 19, connected to the belt-wheel 20 of theelevator 10 by the belt 21. 22 designates a gear-wheel mounted upon saidshaft within said bracket, and 23 an intermeshing pinion also mountedupon a short shaft journaled upon said bracket and extending at rightangles to the short shaft 18. Said shaft carries operatively aneccentric 21-, which is connected in the customarymanner to the pitman25, pivotally connected at its opposite ends, as at 26, to the sifter13,in order that the operation of the said eccentric maycause the rapidreciprocation of the sieve, to the end that the grain which isdischarged upon one end of said sifter may pass through the same and thelower deck below, and consequently avoid a second and unnecessarypassage through the cylinder.

27 designates a discharge-spout at the upper and front end of the casing11, and 28 a connecting-spout whereby the tailings minus the grain maybe conducted back to the cylinder, if desired, that the same may beagain acted upon by the latter.

As an inconsequential number of heads after being once acted uponcontain any grain, it is obvious that it may be of advantage in order toincrease the output of the machine to discharge such heads, togetherwith their tailing products, upon the ground instead of taking them backinto the cylinder. To accomplish this, I provide a spout 28 with staples2.), and engage them with hooks 30, carried by the discharge end of theelevator-casing, so that by simply disengaging said hooks and staplesthe spout may be turned from the cylinder-box in the opposite directionand resecured in position quickly and easily. After all of the straw hasbeen threshed this accumulation of tailings may be passed through thecylinder and the few heads containing grain again operated upon.

A recapitulation of the entire operation it is thought is unnecessary,as the operation has been referred to in connection with the details ofconstruction.

Thus it will be seen that I have produced attachments for threshingmachines which will be found to materially increase the output of suchmachines and which are of such inexpensive construction that they arewithin the reach of all who need them. It is also obvious that theseattachments are practically indestructible, as, they are exceedinglysimple, strong, and durable.-

It is to be understood, of course, that various changes in the form,proportion, detail construction, and arrangement of parts may be madewithout departing from the spirit and scope or sacrificing any of theadvantages of my invention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

In a threshing-machine, the combination of an upwardly andforwardlyinclined elevator 9, having its lower end adapted to receivethe tailings from the feed-spout of the machine, and provided with adepending dischargespout 16, at its upper end, a second elevator 11, atthe opposite side of the machine, and provided with a dependingdischarge-spout at its upper end, a sifter 13, extending transversely ofand suspended from the machine, and adapted to receive the tailings fromthe spout 1G, and discharge them into the lower end of elevator 11, aneccentric 23, linked to the Sifter, a rectangular frame 17, carrying theshaft of the eccentric, and a second shaft, intermeshing gear-wheelsupon said shafts, and gearing between the first-named elevator and shaft18, all arranged substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL S. LONG.
